Skysay MCP: give Grok Bot a real phone number in 100+ countries
At a glance
Skysay’s hosted Streamable HTTP MCP (https://api.skysay.ai/mcp) lets Grok Bot check coverage, request numbers, place approved outbound calls through a hosted voice agent, and send SMS—OAuth/PKCE, separate call vs SMS approval, no local Twilio bridge. Start read-only with account_overview; outside US/CA/UK/MX outbound often needs carrier review first. This workflow is listed under Grok-Bot, MCP, telephony, consumer-agents, HITL, monetize.
Marc Lou’s MailCheap exposes Streamable HTTP MCP at https://mailcheap.ai/mcp so ChatGPT, Claude and Grok Bot connect with OAuth (no key to copy); Claude Code, Codex and Cursor use a bearer API key. Agents can draft campaigns, send tests, schedule issues and read stats; schedule/send tools are marked destructive and ask before sending. Open-source / self-host option; pay only for SES-style sends vs beehiiv-class plans.
MIT Go daemon + git hook reviews every commit with the CLIs you already pay for—Codex, Claude Code, Cursor, OpenCode, and first-class Grok Build (grok / grok-build). Findings stay in a ledger until closed; agent hooks push open review IDs back into the session for /roborev-fix before context goes cold. Reviews stay on your machine.
Skysay’s launch post positions agent-native telephony—real numbers, calls, SMS—as MCP tools described in llms.txt, with client recipes for Grok Bot and other assistants. Pattern for builders: expose billable / regulated actions as scoped MCP tools with read-only first, quotes before spend, and carrier-review gates per country.
Kondo’s WhatsApp MCP (Streamable HTTP at mcp.trykondo.com/mcp) lets Claude, ChatGPT, Cursor, Claude Code and Copilot search chats, read messages, draft replies, label, reminder and archive while Kondo Desktop holds the local WhatsApp session—no send tool, so nothing leaves as a message until you press Send. Relay keeps chat content off the cloud; Desktop must stay open. MCP on Business/Enterprise plans; install skill at trykondo.com/skills/kondo-whatsapp.md.
